  1. p = 1 / [ √(1 - (v^2/c^2)) ] p [ √(1 - (v^2/c^2)) ] = 1 squaring on both sides to get rid of the sq.root p^2 (1- (v^2/c^2)) = 1 1 - (v^2/c^2) = 1 / p^2 v^2/c^2 = 1 - (1/p^2) v^2 = c^2...

  3. Let v = (f, g, h). Computing determinants repeatedly yields ∇ x v = (h_y - g_z, f_z - h_x, g_x - f_y) ==> ∇ x (∇ x v) = ((g_xy - f_yy) - (f_zz - h_xz), -[(g_xx - f_xy) - (h_yz - g_zz)], (f_xz - h_xx...

  4. 50/v = (1/5)^(1/5) v = ((1/5)^(1/5)) × 50 Find 50 divided by the fifth... it's a quintic, so there's four other (complex) roots v = 50 5^(1/5) This is 50 5^(1/5) 1^(1/5) which is...

  8. sin v + (cos v) / 4 = 0 => sin v = - (cos v) / 4 => (sin v) / (cos v) = -1 / 4 => tan v = -(1 / 4...by [a^2 + b^2 = c^2], c^2 = 1 + 16 => c = root17 Thus, cos v = adjacent / hypotenuse = 4 / root17. Since either [sin v ] or [cos v...

  9. One possibility is v(x) = x^2 and u(x) = 1/(x + 1), because with this choice you have u(v(x)) = 1/(v(x...x)) = (u(x))^2 = 1/(x+1)^2. How did I come up with u and v? I just stared at the two formulas and thought, for...

  10. If v is half of w: v = w/2 and u is the mean of v and w: u = (v + w) / 2 And you know it's a triangle...w = 80 Now that we have w we can solve for v and u: v + w = 120 v + 80 = 120 v = 40 u = (v + w...
